Anti-PSMB2 Antibody

This unconjugated polyclonal antibody from Antibodies.com targets PSMB2, a constitutive beta-type subunit of the 20S proteasome core particle. Raised in rabbit, the reagent binds epitopes within the catalytic beta-ring that contributes to ubiquitin-dependent intracellular protein turnover. The antibody is validated for Western blot, immunohistochemistry, and immunofluorescence workflows, with reactivity confirmed against human, mouse, and rat tissue. Supplied as a 100 µL liquid aliquot, it supports multi-experiment use across lysate and section-based preparations. Polyclonal reagents recognize multiple epitopes on PSMB2, which is useful when probing truncated isoforms or post-translationally modified forms of the subunit. Researchers studying proteasome assembly, NF-κB signaling, ER-associated degradation, and oncology-relevant degradation pathways commonly track PSMB2 expression to gauge proteasome activity and composition in their model systems.
